APPARATUS FOR GENERATING ACETYLENE GAS.

SPECIFICATION formingpart of Letters Patent N o. 698,044, dated .Apri1 22, 1902.

Application filed ll'uly 25, 1898.

To tZZ whom it may concern:

Be it known that I, JEAN NoUZARET,-a subject of the King of Belgium, and a resident of Brussels, Belgium, have invented certain new 5 and useful Improvements in Apparatus for Generating'Acetylene Gas, of which the following is a specification.

This invention relates te an apparatus designedto produceacetylene gas for domestic lo purposes and to work automatically while being of such a simple and safe construction as to enable it to be worked and attended to by any one not specially trained for the purpose.

In order that the invention maybe clearly understood and readily carried into effect, reference will'be had to the accompanying drawings, in which- Figure 1 is a vertical longitudinal section of an apparatus constructed according to 2o this invention. Fig. 2 is a transverse section through the generator and recharging apparatus. y

It may be mentioned that the drawings serve merely as an illustration by way of an example of the apparatus and that the proportions and details of construction, as well as the general arrangement, may be varied to l suit particularV circumstances.

The apparatus broadly consists of a gener- 3o ator A, adapted to be charged with the carbid or carbureted calcium from an automatic charging apparatus B, of a gasometer C, and

of a purifier F. The two last-named parts may be of any ordinary or known construc- 3 5 tion, and it is therefore only necessary to describe the generator and its charging apparatus. Y

The generator A here shown is of cylindrical form standing onend and closed at the 4o top and has at its lower end a conical or funnel-shaped portion, which is provided with an outlet-valve D, as shown. To one side of the cylindriealportion` of thisgenerator is fixed a pipe E, rising above the generator and formed with an enlarged mouth arranged in proximityof the charging apparatus B. This latter consists of a horizontally-arranged carrier-plate P, rmly secured to a vertical spindle G and supporting a number of `buckets O 5o O, distributed around its circumference, each Serial No. 686,862. .(No model.)

of which containsa predetermined charge of carbid. These buckets are suspended by pivots and are capable of being tipped in order structed as to have a tendency to tip automatically, and this may be effected either by placing the pivots out of center or by weighting the front of the bucket, a pivoted catch II being Yprovided to automatically lock the buckets and retain them in their normal or upright position by engaging in an eyepiece I on the buckets. The catch together with the bucket Yheld by it revolve with the carrier-plate P, and they pass at the Arequired movement beneath a fixed incline J, whereby they are disengaged from the bucket and allowed to tip forward, so as to discharge the carbid with the mouth of the pipe E.

On the spindle G,but below the carrier-plate P, is a pulley K, controlled by a rope or the like having a weight M and passing over a guide-pulley, as shown. The tendency of this i pulley is to revolve the entire charging apparatus; but its motion is checked by pivoted and forked lever L, adapted to act against two series of pegs provided in the sides of the said pulley. These pegs are so arranged as to permit of an angular movement of the pulley K at eachcomplete oscillation of the forked lever L equal to the distance between two consecutive buckets. By thisarrangement each complete oscillation of the forked lever L causes one of the buckets O to arrive in close proximity to and to be discharged into the pipe E. The lower end of this pipe E extends into the interior of the generator and so prevents gas-bubbles from rising vertically or by capillary action into such pipe.

The gas generated in the interior of the generator is balanced by a column of water contained in a vertical pipe N, in communication with the generator by an opening situated somewhat above that of the pipe E and pro- IOO tected against the entrance of gas-bubbles by an inclined screen or shield Q. This pipe N is provided with an overflow-tube R, through which the excess of water from the generator is allowed to escape, while serving at the same time as a safety device for limiting the maXi mum pressure of gas in the generator.

The gas generated in the generator iiows through a bent tube S into the gasometer C of sufficient capacity to receive the gas generated from a charge of carbid, the gas causing thevbell of the gasorneter to ascend with its uppermost position and then to descend gradually in accordance with the consumption of the gas. O-n the said bell is secured a tappet T, which is so arranged as to strike against the tail end of the forked leverL when the bell C reaches its lower position, and thereby causes a fresh charge of carbid to be discharged into the generator, whereupon the bell ascends again. The forked lever L now being disengaged from the tappet T is returned to its former position by means of a spring V. This method of charging repeatedly and only in small quantities permits of both the gasometer and the generator being of small size, While yet being of a working capacity limited only by the number of buckets carried by the charging apparatus. These buckets may be arranged to be recharged during the operation of the apparatus, and in such case the operation is only interrupted for the purpose of removing through the plug or valve D the residues which accumulate in the lowerpart of the generator, which, however, is only required to be cleaned at long intervals, owing to the prolonged form of its lower end.

Having now particularly described and ascertained the natu re of my said invention and in what manner the same is to be performed, what I claim as new, and desire to secure by Letters Patent, is

In combination in an apparatus for generating acetylene gas, a horizontally-revolving carrier, a series of buckets pivotally supported on said carrier, catches for holding said buckets from tipping, and stationary means for successively operating said catches as the carrier moves,an escapernent mechanism controlling the carrier and including a horizontal pulley connected with ldie carrier having pins, a weight for moving said pulley, a forked lever L for controlling the pulley, the bell and a tappet T on said bell for operating the forked j lever, substantially as described.

In witness whereof l have hereunto set my hand in presence of two witnesses.
